I have several of the small kohler  90,an 91 some complete and some not. Some of them do not have a blower cover on them, is there a way to tell them apart without taking the head off and measuring? Some have an  id. tag an some don’t.  Thanks. Tim

I don't think that pulling the head & measuring would help you find your answer. I believe that the K90 and the K91 have the same stroke & bore (2.375" bore x 2" stroke). Appearance wise I do not know how to tell the difference and most if not all of the parts will interchange. The one difference that I do know of is the governor setting, the K90 is rated at 3.5hp at 3600RPMs and the K91 is rated at 4hp at 4000RPMs.

If the heads are original, the K90s will have angled/curved fins and the K91s will have straight fins.
